Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023860, here are decompositions:

3 + 1023857 = 1023860
109 + 1023751 = 1023860
127 + 1023733 = 1023860
139 + 1023721 = 1023860
163 + 1023697 = 1023860
283 + 1023577 = 1023860
373 + 1023487 = 1023860
499 + 1023361 = 1023860

Showing the first eight; more decompositions exist.
